Abstract
. Uhan, T.S. 2007. The Effect of Baculovirus Crocidolomia pavonana (BVCp) Concentration Againts Crocidolomia pavonana Zell. in a Greenhouse. The purpose of this experiment was to determine the best concentration of BVCp in suppressing C. pavonana growth. This experiment was carried out at Laboratory of Pest and Diseases and in the Greenhouse of Indonesian Vegetable Research Institute, Lembang District, Bandung , from November 2001 to February 2002. The experiment was arranged in a randomized block design with 6 treatments and 4 replications. The treatments were 4 extract concentrations of C. pavonana larvae which were infected by BVCp (5, 10, 20, and 40 larvae per l of water), formulation of Bacillus thuringiensis (Dipel WP® 2.00 g/l), and control. The results showed that after 6 days (144 hours) of application the extract of 40 C. pavonana larvae infected by BVCp per l of water (116.64 x 1010 PIBs/ml) caused the highest larvae mortality (94.45%). The fastest LT50 was 64.81 hours after application
